Electrically adjustable side mirrors — description (Chevrolet Trailblazer 1)

1. Electrically adjustable rear view mirrors have two electric motors for adjusting their position in two planes (up-down and left-right).

2. The switch has a distributor that directs the current to the left or right mirror. With the ignition switch in the ACC position (without starting the engine) and, having lowered the windows, move the left and right mirrors alternately to all possible positions, using the switch.

3. Listen to the sound of the servomotors working.

4. If you hear the sound of the servomotors working, but the mirror glass does not move, then the fault lies in the mirror drive mechanism. Mirrors cannot be repaired - if necessary, these elements are replaced as a whole (see chapter 11).

5. If the mirror glass does not move and there is no sound of the electric motor, inspect the corresponding fuse (see subsection 3).

6. If the fuse is found to be in good condition, remove the control switch. Contact a qualified or authorized service station to inspect the circuit breaker for an open circuit.

7. Inspect the ground loop connections.

8. If the mirror does not work after performing the above checks, remove it and check the voltage supply to the wires.

9. If voltage is not supplied when the switch is moved to any of the possible positions, examine the section of the circuit between the mirror and the switch for an open or short circuit.

10. If the presence of voltage is confirmed, remove the mirror and check its functionality by connecting additional wires from the battery. If the functionality is not confirmed, replace the mirror.
